Denotes the interval in seconds, at which the route max threshold notification will be re-issued after the maximum value has been exceeded (or has been reached if mplsVpnVrfConfMaxRoutes and mplsVpnVrfConfHighRouteThreshold are equal) and the initial notification has been issued. This value is intended to prevent continuous generation of notifications by an agent in the event that routes are continually added to a VRF after it has reached its maximum value. The default value is 10 minutes (600 seconds). If this value is set to 0, the agent should only issue a single notification at the time that the maxium threshold has been reached, and should not issue any more notifications until the value of routes has fallen below the configured threshold value.
